Listening to Al Greens 2008 album Lay It Down the guitar playing throughout the whole album really caught my ear, turns out the parts were played by a musician named Chalmers Edward "Spanky" Alford (May 22, 1955 – March 24, 2008)

Really tasteful playing for the song, the guitar tone is really nice too.
